I don't see an agitator, how does it get the clothes clean?

Gravity.

The clothes falling down from the upper half is described on the slides, so I assume the rotation isn't fast enough for the clothes to stick to the walls, or it has an elliptical rotor to make sure there a speed difference ?

(edited as I'm not sure how it exactly works)

Tumbling, just like a generic front-load washing machine.

Oh, I would never buy one of those
